Abstract |
Star formation in galaxies is tightly connected to the dust grain formation through the production of heavy elements. Observationally, it is the most direct to measure the star formation rate by the amount of ionizing UV photons, but dust formed by the star formation scatter and absorb these photons, and finally re-emit the energy at the IR. Hence, it is necessary to observe galaxies at both UV and IR to explore their star formation in the cosmic history. In this presentation, first we introduce a statistical method to handle the two datasets which have been treated independently at each wavelength in a unified manner, and reveal the star formation in galaxies hidden by dust. |
